FLAP-LAYER.

"SPECIFICATION forming part of Letters Patent No. 759,273, dated May 10, 1904. Application filed July 26, 1901. Renewed September 12, 1903. Serial No. 178,014. (No model.)

' as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to channelflap-laying machines.

One form of channel-flap-ltying machine which has gone into extensive use consists of a rotary tool provided with flap-laying blades. While this machine has produced excellent results, it has not proved entirely satisfactory in operation, as the operator often experiences difficulty in so manipulating the shoe as to cause the blades to lay the channel flap smoothly and evenly, especially at the toe portion of the sole. This is due to the fact that the flap-laying blades are arranged transverse to the direction of rotation of the tool, and consequently unless the shoe is tilted in various directions while in contact with the tool the blades act successively on the channelflap in the same direction. The channel-flap is thus stretched always in the same direction and is not laid smoothly and evenly, especially at the toe portion of the sole. Moreover, the most natural position for holding the shoe and the one in which it is ordinarily held brings the channel-flap parallel with the flaplaying blade acting on the shoe. The blade therefore strikes the channel-flap at the base and wipes across it transversely. This move ment of the blade subjects thefiap to a some,- what harsh treatment and tends to tear the flap from the solo.

The object of the present invention is to provide a channel-flap-laying machine comprising a rotary tool in which the flap-laying blades are arranged to act on the channel-flap so as to lay it smoothly and evenly and at the same time avoid subjecting the flap to harsh treatment.

With this object in view my invention consists in providing the rotary tool of a flaplaying machine with flap-laying blades arranged at difi'erent angles to the direction of rotation of the tool. By so arranging the blades the channel-flap is acted upon by the blades in diflierent directions and is stretched and rubbed so as to lay smoothly and evenly without skilful manipulation of the shoe by the operator. Preferably certain of the flap laying blades are arranged oblique and alternately oppositely inclined to the direction of rotation of the tool and the remaining blades are arranged transverse to the direction of rotation of the tool and are located be tween the first-mentioned blades. By this arrangement of the blades the channel-flap is rubbed longitudinally by one of the oblique blades, then transversely by one of the transverse blades, and then longitudinally in the opposite direction by one of the oblique blades, the action being very similar to that of arubstick in the hands of an operator in laying a channel-flap by hand.

WVith the rotary tool referred to I preferably combine a rotary brush arranged to act upon the sole of the shoe and upon the channel-flap in proximity to the blades of the ro-. tary tool. This brush acts to remove from the bottom of the sole and the channel-flap particles of dust, dirt, wax, and cement adhering thereto and also supplements the action of the flap-laying blades of the rotary tool in laying the flap. In order that this brush may more effectually aid in the channel-llap-laying operation and also act to break up and remove the wet cement adhering to the channel-flap and to the surface of the sole, it is provided in addition to the usual flexible bristles with comparatively stifl' strips in the nature of stiff bristles, which I have termed scrapers and shall refer to as such herein.

WVhile my invention may be embodied in many different constructions, apreferred form thereof is illustrated in the accompanying drawings, in which Figure 1 is a face view of a ring provided with flap-laying blades arranged according to my invention. Figs. 2, 3, and 4 are sectional views on the lines 2 2, 3 3, and 4 at of Fig. 1. Fig. 5 is a View in longitudinal section of a portion of a flap-laying machine comprising my improved flap-laying tool and rotarybrush.

Fig. 6 is a face view of a portion of my improved brush.

Referring to the drawings, 1 indicates a ring, on one face of which is formed the Zigzag rib 2, constituting a series of flap-laying blades, which are arranged oblique to the circumference of the ring and which are alternately oppositely inclined to the circumference. Alternating with the oblique blades are blades 3, extending radially of the ring. When the ring 1 is in position in the machine, it is rotated about an axis concentric with the ring, and it will be seen that the blades formed by the Zigzag rib 2 are arranged oblique and alternately inclined to the direction of rotation and that the blades 3 extend transversely to the direction of rotation. The ring 1 is secured to the rim of a wheel 4,1oosely mounted upon a driving-shaft 5. A collar 6 is secured to shaft 5 and is provided with arms 7 on which are mounted rollers 8, arranged to engage diametrically opposite slots in the end of the hub of wheel 4. A coiled spring 9 surrounds the shaft and is interposed between a collar 10, secured to the shaft and the hub of wheel 4:.

The above-described construction is such that the wheel 4: and ring 1, secured thereto, are rotated by the shaft, but can move longitudinally of the shaft against the tension of the spring when a shoe is brought into contact with the flap-laying blades, which thus strike the shoe with a yielding impact.

The brush which I have shown in the drawings consists of an annular back 11, from which the flexible bristles 12 and relatively stiff scrapers 13, of whalebone or other suitable material, project into a position to engage the bottom of the sole and the channel-flap of a shoe held in contact with the flap-laying blades of ring 1. The back 11 is secured to a ring 14, which is adjustably secured to the wheel 4 by means of screws 15, passing through slots in the spokes or arms of the wheel and screwing into lugs projecting from the ring.

In the operation of the machine above described the flap-laying blades act successively to rub the flap progressively in one direction longitudinally of the flap, then transversely, then progressively in the opposite direction longitudinally of the flap, and then again transversely. The flap is thus stretched and laid smoothly and evenly at all points without any special skill on the part of the operator. The scrapers 13 break up any cement or wax adhering to the surface of the sole or channelflap and enables the same to be removed by the bristles 12 even if the sole is wet, and the bristles and scrapers by acting on the channelflap supplement the action of the flap-laying blades in laying the flap.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a flap-laying machine, a rotary tool provided with flap-laying blades arranged at different angles to the direction of rotation of the tool, substantially as described.

2. In a flap-laying machine, a rotary tool provided with flap-laying blades arranged oblique to the direction of rotation of the tool and with flap-laying blades arranged transverse to the direction of rotation of the tool, substantially as described.

3. In a flap-laying machine, a rotary tool provided with flap-laying blades arranged oblique and oppositely inclined to the direction of rotation of the tool, substantially as described.

4. In a flap-laying machine, a rotary tool provided with flap-laying blades arranged oblique and alternately oppositely inclined to the direction of rotation of the tool, substantially as described.

5. In a flap-laying machine, a rotary tool provided with flap-laying blades arranged oblique and alternately oppositely inclined to the direction of rotation of the tool and with flaplaying blades located between said blades arranged transverse to thedirection of rotation of the tool, substantially as described.

6. A flap-laying machine, having, in combination, a rotary tool provided with flap-layingblad es arranged oblique and oppositely inclined to the direction of rotation of the tool, and a rotary brush provided with flexible bristles and with comparatively stiff scrapers, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
